What Web Browser is Fastest for Windows in 2011?

We are always looking for more efficient ways to do things in the office and one of the things I recommend to the guys at work is to dump IE8 and use something like chrome. Its amazing how many people still use IE8 and just think its just the PC they are using or the network they are on.
Our old friends over at Legit Reviews have compiled this outstanding review/guide testing 15 browsers out there today.:

For the past two years we have taken the time to stop doing hardware and do give web browsers a chance at the spotlight. This year is no exception and we will be taking our most in-depth look at web browsers ever. Back in 2009 when we started doing performance testing on web browsers we ran the Peacekeeper benchmark and called it a day. The next year we didn't feel like that was enough, so we tested even more browsers and also included SunSpider Javascript benchmark results. This year we wanted to trump what we did the year before, so we have taken the time to run seven tests on 15 different browsers. We wanted this article to be your 'one stop shop' to help you determine what web browser is fastest and best suites your needs.
